Fluid Dynamics - The Kaye Effect

[gumpzilla]

How viscous does the fluid have to be before this starts happening, I wonder? I know dick about fluids.

That's the craziest [censored] thing I ever saw.

It seems like it's just following the path of least resistance.

Is your paper up anywhere? I'd like to read it. Perhaps it would teach me enough so that I no longer thought that this behavior made any sense.

And clearly that's the path everybody would have predicted. Have you ever seen liquids do this? EDIT: I find this brand of superficial non-understanding particularly grating because it's super common among physicists considering problems that they consider too lowly for them. Almost always they end up not having a clue.

I asked for the dissertation in the hopes that I'd increase my understanding of fluid dynamics. I admitted that my ignorance could be the reason for the simplistic explanation that I come up with for it. I offered no "why" because I have none.

If I leave off the commentary and shoot straight to the questioning would that be more acceptable?

It is available online. It really isn't "on" fluid dynamics; rather I used computational fluid dynamics to simulate mass transfer in binary stars. If you still want the link, PM me.

It's possible I misinterpreted the nature of your statement. If so, I apologize.

Here's a story that typifies what I'm talking about. Years ago, upon first arriving to grad school, we had a workshop for TAs. We were supposed to come in with something that we were going to lead a discussion on with other grad students. My roommate brought in one of these toys. Upon demonstrating the weird behavior (spun one way, it's stable, spun the opposite direction it rattles and begins spinning in the stable direction), some guy observes "Oh, that's just symmetry breaking." Oh, really? Thanks! NOW I understand it perfectly.

I love rattlebacks.

[suzzer99]

That is awesome. Some of those other videos are pretty cool as well. Check out the Bugatti, anti-helium and the high-voltage inspector.

I see what you mean. I'll try to do a better job of providing more detailed guesses so that there are legit holes to poke if they exist, and also offer up some real answer if I happen to be thinking along the correct lines. My "guess" was too open to provide either.

I found this link through wikipedia, has a pretty easy-to-understand explanation:
